This book is the result of research carried out as part of a final year project for a Master's degree in Didactics. It focuses on the effectiveness of flashcard strategies in the teaching/learning of vocabulary in FLE situations among Algerian learners, more specifically those in the second middle year at the BOUAZZA Belkacem secondary school in the town of Saïda. We carried out a questionnaire aimed at FLE teachers, with the aim of finding out their attitudes to the effectiveness of this technique. The results were reinforced by an experiment we carried out with the same learners.
